Dunno, but all this seems bullshit.
First, I believe all this kinds of riots are just group/herd behaviour ( http://en.wikipedia.org/wiki/Herd_behaviour ) and any blackberry "coordination" was probably some innocent people inviting others to join the protest.
Come on those are just a bunch of angry kids that thought they were "doing the right thing" by raising hell and going against each and everyone...
No major coordination.. no major plots or conspiracies.
Going after everybody's bbms just to try to find out who were the rioters is just plain Orwellian.
Finally, blackberry stepping up publicizing that on twitter looks just like "hey hey people! Look at us! We want to protect you! We still exist and we are responsible!"
If it was that important they wouldn't make their support public...
